Pre-heat Storage of Solar Water Heating Systems
In pre-heat storage, the energy is transmitted from the primary system. This is integrated with any other heat sources situated further ‘downstream’. These additional heat sources top-up any temperature shortfall from the solar-generated pre-heat water store before final distribution. This refers to heat sources intended to contribute to average daily demand, it does not mean manually-controlled sources used for occasional boost beyond mean daily demand or automatic sterilization routines. A suitable pre-heat solar the store will maximize the safe displacement of fossil fuel and the most significant variable in a store’s performance is the volume, which should be sized for household use or the absorber area If an absorber is of the highest efficiency then, in order to achieve the maximum collector performance, higher rates of solar storage may be required – up to 100 liters per square meter of the absorber for some collector types. Such very large stores can be further improved...
